Voters in some areas have been claiming that they were turned away from polling booths after being told their names were not on the register, despite having seemingly registered weeks ago.

Becky Timmons told the Guardian that she and her husband received polling cards after registering in September, but only he was able to vote.

“When I went along and said my name and address they said that I was not on the list,” said Timmons, from Campton, Bedfordshire. “Then the official said: ‘Oh, we have actually had three other people like this, so let us check.’ They phoned up the council but I was still unable to vote. Then she suggested it was some sort of computer error.

“It made me quite cross. If there were four that happened in our local village then you wonder if it was part of a nationwide thing.”

Kieran Robertson, in North Oxfordshire, said he had registered online to vote on 28 May and had received an email confirming he was registered. After checking and rechecking with the council earlier this week he turned up at his local polling station and was told that he was not able to vote.

“It seems like the national computer system went fine but when that tried to send the details to the council system something went wrong and nobody was informed,” said Robertson, who said he will complain. “It leaves you thinking about our status as a democracy. I have not been able to vote, which means that we are not a democracy in some ways.”

A spokesperson for the Electoral Commission said that it was not aware of any major problems being reported in relation to voting.

Voters report being turned away from EU referendum polls

Farage says Eurosceptics 'winning the war', even if they do not win tonight.

Here are the key quotes from Nigel Farage.

I have to say, it has been a long campaign - in my case 25 years. And whatever happens tonight, whoever wins this battle, one thing I am completely certain of is that we are winning this war. Euroscepticism was considered to be fringey, fruitcakey, to quote the prime minister, and now it looks like tonight maybe just under half, maybe just over half the country, is going to vote for us to leave the European Union ...

The Eurosceptic genie is out of the bottle - and it will now not be put back.

But, perhaps even more remarkably the biggest change from this referendum is not what has happened in the United Kingdom. It is what has happened across the rest of the European Union. We now see in Denmark, in the Netherlands and even in Italy up to about 50% of those populations want to leave the European Union.

I hope and pray that my sense of this tonight is wrong. And my sense of this - and no, I’m not conceding - is that the government’s registration scheme, getting 2m voters on, a 48-hour extension, is maybe what tipped the balance. I hope I’m wrong.

Farage says he thinks Remain has won.

He says government’s decision to change the law to allow a 48-hour registration extension may have tipped the balance.

He says Eurosceptics are “winning this war”, even if they do not win tonight.

Deborah Mattinson is asking how a divided Britain can heal itself after the EU referendum.

The EU Referendum campaign may not have clarified all the issues in voters’ minds, but it has shone a light on a growing chasm in the country. People divided by geography, social class, age, education and income are even more sharply divided by outlook. Whether to remain in the EU or leave is just one of many of those differences. Whatever the outcome on Thursday, it is unlikely to heal our fractured nation.

With the ballot sampling under way, a pattern is now emerging in Glasgow, with middle-class areas voting decisively to remain while working-class areas like the east end are neck and neck with leave.

Estimates of turnout around the country are solidifying around 70% – higher than last month’s Scottish parliament elections but less than the 2014 independence referendum. Turnout in Scotland looks like being a wee bit less than England but, having urged the electorate to the polling booths four times in the last three years, this is no great surprise.

I’m also told to look out for surprisingly high leave votes in solid SNP areas like Dundee and Inverclyde; perhaps prompting some soul-searching for the party’s high command.

Sterling has slipped back from its highs against the dollar on talk that the Newcastle result will only be a marginal win for Remain, while Sunderland is said to be strongly leave. The pound is now at $1.4897, having earlier hit $1.5018.

If Leave really win Sunderland by 20% and Remain win Newcastle by only small margin, upset back on the table.

My colleague Jill Treanor is on the trading floor at currency trader WorldFirst. Its chief economist and head of currency strategy Jeremy Cook said: “These markets are so thin, so skittish, [the pound] could really come off on any thing.”

There is some chat that hedge funds had been doing their private polling to get one step ahead of the market. Cook too has heard about hedge fund exit polls and apparently people were being asked how they’d voted by financial analysts in some constituencies. “If a hedge fund had a scent of something sterling would have been hit a lot harder,” Cook says. A veteran of late night election campaigns, Cook says this is the classic time for rumours to start while count comes in. “If a hedge fund had a scent the market had mispriced this and a leave vote was likely sterling would be a lower than this”.
